Patent GB-2326235-A (GB)
Title: Measuring thickness of cement kiln linings
Inventor: HARPER MARK
IPC: G01B17/02
Filed: 1997-06-12
Abstract: A method and apparatus are disclosed for measuring the thickness of the layer of refractory brick 15 on the inside of the steel wall 5 of a cement kiln and of any layer of clinker 19 adhering to the inner face of the brick layer. The method may be applied from the outside of the kiln during normal operation. The method depends on the measurement of the response of the kiln wall to an impulsive force applied at a point 17 by a hammer 13. The vibration response at the point is monitored by a transducer 7 so as to determine the mechanical impedance at the point. The vibration response is, at the same time, monitored by a transducer 9 at a small distance from the point so as to determine the velocity of flexural waves in the kiln wall. Thickness can then be calculated from the determine impedance and velocity and from a knowledge of the thickness of the steel wall and of the density and elastic property of the steel, the brick and the clinker.

Title: Gear recognition method and circuit arrangement
Inventor: FRIEDRICH ARNO
IPC: F16H59/70
Filed: 1997-07-31
Abstract: A gear recognition method comprises detecting, via second speed sensor 15, a velocity V of a vehicle and, at the same time and over the same period, establishing an engine speed N by way of first sensor 14. Signals representing the velocity V and engine speed N are relayed to a control unit 18 which calculates a V/N ratio and compares this ratio with a known transmission limit ratio (see fig 2) already entered in control unit 18. The calculated V/N ratio must lie within a narrow tolerance band around the known limit ratio in order to recognize a gear as engaged. If clutch 19 is determined, via sensor 20, to be disengaged the alteration of V/N, ie * capital Greek delta *(V/N)=V/N NEW -V/N OLD is calculated or the derivation with respect to time (or gradient) is established and evaluated. If V/N changes more quickly than a predetermined threshold value, it is established that no gear is engaged.

Abstract: A video scrambling and descrambling arrangement utilizes plural scrambling characteristics including a predetermined scrambling waveform (15) and a selectable one of a plurality of phase relationships (50-57) with respect to the video signal (10) to be scrambled. Descrambling is achieved by combining (117) with the scrambled video signal a correspondingly phase shifted, inverted version of the scrambling signal. Scrambling and descrambling can be implemented in analogue or digital forms. The information required to achieve descrambling is contained in the scrambled video signal, preferably in an unscrambled portion (91) thereof.

Patent GB-2322494-A (GB)
Title: Spacecraft with parallel amplifiers and redundancy
Inventor: WOLKSTEIN HERBERT JOSEPH
IPC: H03F1/52
Filed: 1998-02-11
Abstract: A spacecraft includes a plurality of paralleled RF amplifiers. Each paralleled power amplifier (206) includes a signal splitter (222) which produces two nominally equal-amplitude signals, and a signal combiner (242) which combines appropriately phased signals to produce a sum signal at a sum port (250). The signal combiner also includes a null output port (248). A pair of elemental amplifiers (236, 238) is coupled between the splitter outputs and the combiner inputs. In order to allow for phase drift of the elemental amplifiers, at least one phase shifter (258) is associated with one of the elemental amplifiers. A phase control loop is coupled from the null output of the combiner, around the paralleled amplifier arrangement, and controls the phase shifter to maintain the phase within bounds, to maximize the signal at the sum port of the combiner. In order to provide for redundancy, at least one channel (271; 272) of the paralleled amplifier includes the cascade of a phase shifter (258; 259) and a switching arrangement (281) which allows a failed elemental amplifier to be replaced by a redundant unit. No additional phase shifters are required, since the loop phase shifters compensate for differences between failed and redundant amplifiers.

Title: Magnetic channel cathode for a flat panel display
Inventor: BEETESON JOHN STUART
IPC: H01J29/68
Filed: 1998-09-03
Abstract: An electron source, e.g. for a flat panel display, comprises a permanent magnet 102,104 having channels extending between opposite poles. The internal surfaces of the channels are conductive. A cathode (204, fig 2) is located at a first pole of the magnet, at one end of the channels. Each channel within the magnet has a plurality of perforations 106 located on a surface of the permanent magnet. A potential applied between the cathode and the conductive internal surfaces of the channels causes electrons to be received into the channels Each perforation 106 gives rise to a null field region where electrons collect. An electron beam for guidance towards a target can be extracted from the null field region 602 by applying an electric field over the perforation. A variety of kinds of cathode are described, including line filament cathodes and micromachined cathodes.

Title: Encoding a code signal into an audio signal
Inventor: YIN JIA HONG
IPC: G10L25/21
Filed: 1998-10-02
Abstract: Previously as a result of data compression protocol codes hidden into "sync periods" have been degraded or lost as a result of, for example, low pass filtering. The invention overcomes the problem of encoding a code into an audio signal by sampling the audio signal and embedding the code into a suitable portion of the audio signal so that the code is hidden within a sufficiently energetic portion of the audio signal. The portions are selected as two notches where the energy of the audio signal in the notch is low compared to energy over a wider band.

Abstract: An extra length accommodation structure (10) for optical fibres comprising a base (12), and first (24) and second (44) winding drums pivotally mounted on the base (12). Each of the winding drums (24, 44) may pivot between a position where they are positioned over the base (12), and a position where at least a part of each winding drum (24, 44) projects from the base (12). A splicing portion accommodation structure (14) may be fixed to the base (12) for accommodating a splicing portion, and the first (24) and second (44) winding drums may be mounted on the base (12) by first (22) and second (42) support members respectively. Each of the winding drums (24, 44) may be formed by first and second semi-circular drums (see 24a and 24b in fig. 6A) which are movably connected to each other so that they may be moved between reduced or enlarged diameter positions.
